SMALLWOOD, OF SAULT STE. MARIE, ONTARIO, CANADA, ASSIGNOR TO ALGOMA STEEL CORPORATION LIMITED, RATION OF ONTARIO.

seer-r STE. MARIE, ONTARIO, CANADA, A CORPO- MACHINE FOB BREAKING STEEL INTO SHELL-BLANKS.

To all whom it may concern:

Be it known that I, FRANK SMALLWOOD, a subject of the Kin of Great Britain, and residing at Sault gte. Marie, Province of Ontario,Doniinion of Canada, have invented certain new and useful Improvements in Machines for Breaking Steel into Shell- Blanks, of which the following is a specifi cation.

This invention relates to improvements in machines for breaking metallic bars'into determinate lengths, as may be desired, in

.which the bar is broken by pressure being brought to bear, or a blow delivered on (reference being made to points of support) an overhangin i -bar,'which l ias' been previously nicked at the point where. it is" desired the' break shall .occur, by means of a die; or, by the'rernoval 2 of metal, as by a cutter; or by so'called burning, effected. by means of an oxy' acet lene torch; or by any other suitable met 0d.

The, objeetsof my invention are to effect 26 the desired result expeditiously and economically, by a method in which the operation ma be said to be continuous, the bar to be bro en being fed in one end of the machine, and the portions broken off automatically 80 delivered at the other end; to provide means of adjustment to suit the various sizes of bars to be broken, and the lengths into which same are to be broken and to provide means of applying pressure to the overhanging or 85 canta fver portion of the bar.

The invention consists essentiall of the improved construction hereinafter escribed in detail in the accompanying specification and drawings.

Referring to the drawings, and first to that form of the invention shown in Figs. 1 to 6, A represents ,the frame or body of the machine of suitable shape andsize to support and house the working parts. B represents the supporting member preferably made in the form of a slide, and carrying supporting rollers C turning on shafts D, which su porting rollers are designed to support the Ear 10 of metal or the like which is to be broken. 7

E represents the anvil member located at one ad of the su porting member and preterably provided with means to raise and lower it, whereby it may be raised above the surface of the supporting member, or above the plane of the bottom of the bar.

In the embodiment illustrated, the anvil member E is mounted in a guideway mgroove 11, in which it'is adapted to be raised or lowered by a wedge member F, which is operatively connected to a pressure cylinder G provided with a piston H, the piston rod I of which is connected to and adapted to operate the wedge member F.

.I represents the retaining member adapted to engage and support the side of the bar opposite the anvil member, while the projecting end .of the bar is bein broken therefrom in the manner hereina er described It is provided on the side nearest the anvil member with a removable shoe, filler or Wearing piece 'K, the thickness of which may be varied to suit the dian'ieter or thickness of the bar to be broken. This shoe may be of any convenient construction, as illustrated, it is U-shaped in form and held by the retaining member by means of a link bar 12 extending through slots in the sides 13 and 14: of the shoe and held therein by suitable wedges 15 and 16.

To facilitate the removal of the shoe the side is is pivoted at 17 to the bottom section 18. The retaining member J is held by lugs or flanges 23 on the supporting member B, and preferably forms a part of same.

The supporting member B as a whole, is

adapted .to be adjusted by suit-Mile nuts Z() on the screiv L, which connected to member B in Such :1 way that it is held from rote-ting with respect to the same, the opposite end 01' the screw extending through 2t lug 19 forming part of the fruino.

The nuts 20 also hold nien'il'ier 15 in udjusted position.

This provides it menus to accomplish the adjustment required where it is desired to change the length of the per! into which the bar is to be broken. i

I A tappt screw P is provided in the lower end of the stop member S and by ivhioh the bar being moved in o position for b-reg king is brought'to rest. By adjustment oi? the screw P, the proper relative position of the nick in the barto be broken Ito the point of oolitaot of the bar with the anvil block l; ,can'" be secured.

i The upper end of the stop member S is connected by means of a toggle joint U to upwardly projecting li gs V on the top end of the breaking member M. The toggle joint ,U is so ,eonstructed that falling into .a, position in which three joint pins are in line, it is there brought to rest and forms t rigid st-Ifnt between the lugs V and the upper end of the stop member S, holding the stop member S in proper posit-ion for the pe izforinance of its ,funet-ion as a stop.

The center pin 25 .of rthe toggle joint U is provided 'with it shackle Wtlnough which .isfzrstened one end of a rope or chain X which passes over a sheave or pulley and lies its other end fastened to'the breaking iiiember DI, the rope or chain X bein I tent or nearly so: When the breaking mein er M is its extrel'ne upward position.
